EYVEGLASSES.

SPECIFICATION forming part of Letters PatentNo. 292,479, dated January29, 1884.

Application filed May 6, 1862. (Model.)

To all whom it may concern.-

Be it known that I, IVAN Fox, a citizen of the United States. residingin the city and county of Philadelphia, and State of Pennsylvania,haveinvented' a new and useful Improvement in Eyeglasses, of which thefollowing is a specification.

My improvement relates to that class of eyeglasses having adjustablenose-pieces that are be made of any approved form, as my inventionrelates solely to the nose-pieces N N, the form of which is shownclearly in Fig. 3, where it will be seen that each nose-piece consistsof an inclined bar, a, having arm 12, (preferably curved, as shown.) bywhich the nose-piece is attached with a screw, 0, as shown in Fig. 1, toany convenient part of the frame, but preferably as shown in thedrawings, in which it is screwed fast upon the top of the spring-bow,and is held from moving by means of the sides of the recess in which thearm of the nose-piece and bow are secured. The arm is made integral withthe bar a, and, projecting from a point near the middle, relieves thetorsional strain therefrom.

Said arm also being curved practically lengthens the bar, so that it canbe more readily twisted or bent. The arm I) being of considerable lengthand of soft metal'that is to say, metal that will readily bend, asdesired, and when so bent will retain its form-can be readily twisted,to slightly change the position or angle of the bar to suit the shape ofthe nose; or, by bending the said arms b the bars a a forming thenose-pieces proper, can be readily brought closer together or fartherapart, as desired, and thus the distance of the optical centers of thelenses can be varied as desired.

I am aware that eyeglasses have been made with a curved arm projectingfrom the frame, and having attached thereto a nose-piece; but I do notclaim such as myinvention.

What I claim as new is- 1. The combination, with a pair of eyeglasses,of the nose-pieces N N, each consisting of the inclined bar a, havingthe arm b integral therewith, and projecting from a point near itsmiddle, substantially as and for the purpose specified.

2. The combination, with a pair of eyeglasses, of the nose-pieces N N,formed of comparatively soft metal, each having the inclined bar a andcurved arm I) integral therewith, and projecting from a point near itsmiddle, substantially as and for the purpose specified.

IVAN FOX.
